"Yes, of course," I said.

I was ready to promise anything, if only I could get to Larry and Tina, then back with them to Mary into the Time-cage; and if we were safely out of this era, most assuredly I wanted none of it again. Migul, as I advanced along the catwalk, followed behind me.

"You will kill Tugh?" it reiterated like an anxious child.

"Yes."

I saw that the catwalk terminated ahead under the Power House, where steps led upward. Then I heard a cry:

"Help! Help! Here, inside the dam! Help!"

I stood transfixed, with horror tingling my flesh. The voice came faintly from near at hand; it was muffled, and in the roar of the falling water and lashing spray I barely heard it.

Then it came again. "Help us! Help us, quickly!"

It was an agonized, panting, human voice. And in a chance, partial lull I heard it now plainly.

It was Larry's voice!
